Wildlife Vets Namibia successfully translocated 10 tsessebe antelopes from a Namibian game farm to a private game reserve in Angola last month, before the outbreak of Foot-and-Mouth Disease (FMD).
The operation aimed to move the animals from an area with a thriving population to a suitable habitat where they could establish themselves and contribute to restoring ecological balance.
According to Wildlife Vets Namibia, the operation began early in the morning with the capture of three animals – two cows and a large bull – from one herd.
The team used dart immobilisation, taking advantage of a behaviour that distinguishes tsessebe from many other antelope species.
“Once the immobilising drugs start to take effect, tsessebe often remain standing, unlike most antelopes who become recumbent. We can then hold them by the horns and walk them to the car,” the organisation said.
After being loaded onto the transport truck, the animals received multivitamins, deworming treatment and an anti-tick pour-on.
Wildlife Vets said the immobilising drugs were combined with a long-acting tranquilliser to keep the animals calm for about three to five days. The medication also helped stimulate their appetite during the journey.
With the truck prepared with grass and lucerne in all compartments, the team set out to locate a second herd.
A further seven animals – two cows and five young tsessebe – were successfully darted and captured.
The adult animals were transported separately, while the younger ones travelled together. To reduce the risk of injuries, protective caps were placed over the tips of their horns. The caps were designed to fall off naturally as the animals moved around in the bush.
By late morning, all 10 animals had been loaded and the team began the long journey north.
Cool, overcast weather provided favourable travelling conditions. The team stopped several times to check on the animals before reaching Oshikango at about 23:00.
They crossed into Angola the following morning, where border procedures presented another challenge.
“Border crossings can be stressful, as the process often takes several hours. It was very hot, and eventually we left the Angolan border just before 14:00,” Wildlife Vets said.
The journey continued in more favourable weather, with overcast skies and occasional drizzle.
Road conditions varied, and by about 18:00 the team had reached the turn-off to the reserve. However, the final 60km proved challenging, with thick sandy roads leading to the destination.
The team arrived at the reserve's pre-release boma at about 22:00. The secure enclosure allowed the animals to rest and recover after the long journey.
It also provided easy access to food and water, giving the tsessebe time to regroup and become accustomed to their new surroundings before release.
The following morning, the team found all 10 animals together and appearing relaxed. With the group settled, the enclosure gate was opened that afternoon.
Since their release, Wildlife Vets has received several videos showing the animals exploring their new habitat.
The footage suggests they have adapted well, with the tsessebe walking calmly past vehicles without appearing disturbed.
Although wildlife translocations inevitably cause some stress to animals, the successful arrival and apparent adjustment of all 10 tsessebe marked a positive outcome for the conservation operation.
For Wildlife Vets Namibia, seeing the animals together, relaxed and exploring their new home was a fitting reward for a journey spanning hundreds of kilometres and involving challenging road conditions and international border crossings.
